Silicon carbide is used as a component of the charge, providing the necessary content in the pig iron, silicon and partially of carbon. The use of silicon carbide metallurgical more economical in comparison with ferrosilicon and helps reduce the tendency of liquid iron to chill and also more uniform distribution of spherical inclusions of graphite in ductile iron and more stable silicon content in all cast iron, h is about significantly improves the technological characteristics of the iron-carbon melt and mechanical properties of cast iron. The influence of silicon carbide metallurgical together with uglerodistoi mixture ensures the adequacy of the carburizing process. Silicon carbide contains fewer non-metallic inclusions and impurities of non-ferrous metals than ferrosilicon, a lower content of gases and promotes the release of elemental carbon, forms in the liquid melt centers graphitization. Uglerodsesola mixture is a secondary product thermochemical reactions with the ratio SVAS.: Swab. = 1:7, provides the saturation of the melt particles of carbon, which are the active centers of graphitization and are also a source of silicon to form SiC. Thus, in the present briquette combination of carbon-containing components provides graphitization cast iron due to the complex influence and at the same time provides a synergistic principle of their action. The choice of cement as a binder allows you to produce briquettes of high strength, which substantially reduces the loss of components during storage and transportation. The boundaries of the content components in the composition of the briquette in the first embodiment are justified as follows. Silicon carbide (STF 002222-162-99). When the content within 59-62 wt.% provided Troubleshooting chill in the iron to provide the required content of the cream is Oia. When the content is less than 59 wt.% the silicon content in the pig iron is not responding vintage. When the content is more than 62 wt.% the time response of briquettes increases significantly at low danegerous effect (worsening of modifying the ability of the briquette, deteriorating the form of graphite and, as a consequence, the mechanical properties of castings). Uglerodsesola mixture (TUU 322-00196204.005-99). The number uglerodistoi mixture into briquettes within 21 to 25 wt.% provides a stable carbonizing the ability of the briquettes.

But when the content in the composition of the briquette less than 13 wt.% cement they have insufficient strength, increased litter. When the content is more than 20 wt.% deteriorate the mechanical properties of cast iron, increases the amount of slag. The boundaries of the content components in the composition of the briquette according to the second option proved the following. Silicon carbide (STF 002222-162-99). When the content within 44-48 wt.% provided Troubleshooting chill in cast iron, increasing the amount of ferrite in cast iron and are provided with appropriate content is silicon. When the content is less than 44 wt.% the silicon content in the pig iron is not responding vintage. When the content is more than 48 wt.% you receive an excess of silicon, resulting in reduced strength properties of cast iron due to the heterogeneity of the structure of the metal matrix. Uglerodsesola mixture (TUU 322-00196204.005-99). The number uglerodistoi mixture into briquettes within 36-39 wt.% ensure high and stable carbonizing the ability of the briquettes. When the content in the briquette uglerodistoi mixture less than 36 wt.% carbonizing the ability of their low when the content of its more than 39 wt.% worse shape, size and distribution of inclusions of graphite, which degrades the quality of castings. Cement (GOST 30515-97), for example, grade M-400. In the claimed number provides the necessary strength of the briquettes. But when the content in the composition of the briquette less than 13 wt.% cement they have insufficient strength, increased litter. When the content is more than 20 wt.% deteriorate the mechanical properties of cast iron, increases the amount of slag. The boundaries of the content components in the composition of the briquette by the third variant is proved as follows. Silicon carbide (STF 002222-162-99). When the content within 18-21 wt.% provide the required silicon content, the effect of standard modification that eliminates the chill. When the content of m is her 18 wt.% the silicon content in the pig iron is not responding vintage. When the content of more than 21 wt.% you receive an excess of silicon, resulting in reduced strength properties due to the heterogeneity of the structure of the metal matrix. Uglerodsesola mixture (TUU 322-00196204.005-99). When the content within 62-66 wt.% ensures the sufficiency of the carburizing process. When the content in the briquette uglerodistoi mixture less than 62 wt.% not provided grades of cast iron to carbon, and when the content of her more than 66 wt.% worse shape, size and distribution of inclusions of graphite, which degrades the quality of castings. Cement (GOST 30515-97), for example, grade M-400. In the claimed number provides the necessary strength of the briquettes. But when the content in the composition of the briquette less than 13 wt.% cement they have insufficient strength, increased litter. When the content is more than 20 wt.% deteriorate the mechanical properties of cast iron, increases the amount of slag. The boundaries of the content components in the composition of the briquette according to the fourth variant justified as follows. Silicon carbide (STF 002222-162-99). When the content is in the range of 1-5 wt.% to achieve the effect of standard modification, reducing the number of structurally free cementite. When the content is more than 5 wt.% in the iron you receive an excess of silicon, resulting in reduced strength properties due to the heterogeneity of the structure of the URS of the metal matrix. Uglerodsesola mixture (TUU 322-00196204.005-99). When the content within 79-82 wt.% ensures the saturation of the melt particles of carbon, which are the active centers of graphitization. When the content in the briquette uglerodistoi mixture of less than 79 wt.% not provided a sufficient degree, and when the content of her more than 82 wt.% leads to the release of graphite with liquid iron in the form of sang, which degrades the quality of castings. Cement (GOST 30515-97), for example, grade M-400. In the claimed number provides the necessary strength of the briquettes. But when the content in the composition of the briquette less than 13 wt.% cement they have insufficient strength, increased litter. When the content is more than 20 wt.% deteriorate the mechanical properties of cast iron, increases the amount of slag.
